Latest Patents

Ohnuki's latest patents include an air damper and a lid opening and closing system. The air damper is designed to exhibit an appropriate braking force in accordance with an input load. It features a tubular cylinder with both end portions opened, a piston that moves within the cylinder, and a cap that closes one end of the cylinder. The design includes an annular seal surface on the circumferential surface of the opening, allowing the cap to move or deform along the axial direction of the cylinder. This innovative mechanism ensures that the cap interacts with the seal surface based on pressure changes caused by the piston’s movement.

The lid opening and closing system is another remarkable invention by Ohnuki. This system includes a lid mounted to a recess that can be opened and closed, a locking unit that retains the lid in a locked state, and a lock releasing unit that allows the lid to be opened. The locking unit features a pin that engages with a hole in the recess to keep the lid closed, while the lock releasing unit includes a push button that, when pressed, moves a pushing element to release the lock pin.
